"A further object of the present invention lis to provide a bumperwhich will present an attractive appearance and which will eliminate rattling. l

A still further object is to provide a bumper end construction employing resilienty members to connect the bumper bars together.

Other objects of the invention and features of novelty willbe apparent from the follow- ;ing description taken in connection with the `accompanying drawing, of which Figure 1 is a plan view of a bumper of a v type employing my invention;

Fig. 21s an enlarged plan of the form of end construction shown in Fig. 1, with certain parts shown in sectionon the line 2-2 of Fig. 3;

,Referring tothe drawing, Fig. 1 illustrates 45 a bumper comprising a relatively widev impact Fig. 3 is a front elevation of the end con-V bar 2O and a narrowerrear:barg21, The rear bar is secured to thensual.sideimembersf22 oi?V an automobile,and iscurvedtto meet, the frontbar as at 23 ,aCQOI-dng 1D0-,the LCQmmOD l practice. The front-,and rearbarsare also F50 secured together at "theirdendaaslat 24:1,..and

this invention is directed'to'novelv means'ior securing these `ends together. VVIt shouldbe understood, however, that ,thejjinvention is c not limited to front bumpers but `isfequally 55 c applicable to rear bumpenanQriSji? limitedto any particular Widths or thicknesses of` bars,

it being possibleto vary thelvproportions of A i these members if desired'.

Referring to Figs. 2 and 13,',k that the front or j impactbar 20 isgcoiledat its end so as Ito forma relatively large ,cyling drical portion or Veye 25,.. -T-hefend oftherear bar 21 is likewise ycoiled to forman eye26, this eyebeing much smaller thatgthatformedon 65 the front bar.

Resilientblocks 36, preferably of rubber, are placed Within the eye 25. The construction of these blocks is illustrated in Figs. 4 and 5, Which shoW 'a plan vieW and a sectional View of one ofithegblocks.
